Quantitative analysis of relationship between transitory internal friction and frequency during reverse martensitic transformation in Ni_(49.8)Ti_(50.2) alloy;

Influencing analysis of human activities on frequency of red tides(HABs) in Zhejiang Sea Areas;

The Gradient Analysis with Frequency Variation in Optical-electrical Characteristic of Liquid Crystal Light Valve;

The damping property of foamed aluminum at different strain amplitudes and different frequencies is investigated through measuring the damping of the extensive foamed aluminum at ambient temperature and acoustic frequency with audio frequence internal friction analyzer.

By instrcting on Jcc-220 volt mutuctor computation, the capacitance-hightened voltage value has been found in volt-resisting test with 200 Hi frequence of power source 1 and inductance voltage value of semi-insulation volt mutual inductor has also been found at the same power source by the further analysis of the.

The results show that this new differential amplifier has the capability of wide-band and frequence compensation in comparison with conventional differential amplifier and is a wide-band differential amplifier.

A separable approach based on the SVD of a data matrix is proposed to estimate frequencies and bearings of noise sources by a uniform linear array.

By using CAD software, the influence of mass and spring constant on system natural frequencies and mode shapes is discussed respectively.

The first natural frequency map in working space was drawn,which can be useful for selecting proper working position to avoid resonance or low-order harmonic oscillation.

SiNx thin films were deposited by Plasma-Enhanced Chemical Vapor Deposition (PECVD) methodunder different RF frequency, and the influence of RF frequency on both the deposition process andproperties of the SiNx film were studied.
